This paper treats weight distributions of the coset leaders ofbinary linear block codes. We first present a method for computingthe weight distribution of the coset lead- ers of a given code usingtwo tables each of which stores the weights of the coset leaders of arelated code of the code. Then, the weight distributions of the cosetleaders of the (N,K) Reed- Muller codes, binary primitive BCH codes,and their extended codes with N≤128 and 29≤N-K≤42 that areobtained by using the computing method are given.
